Microsoft at 50 – A journey through code, cloud, and AI

The start of a software empire

Microsoft, the American tech giant, was founded 50 years ago, on 4 April 1975, by Harvard dropout Bill Gates and his childhood friend Paul Allen. Since then, the company has evolved from a small startup into the world’s largest software company.

Its early success can be traced back to a pivotal deal in 1975 involving the Altair computer, which inspired the pair to launch the business officially.

That same drive for innovation would later secure Microsoft a breakthrough in 1980 when it partnered with IBM. A collaboration that was supplying the DOS operating system for IBM PCs, a move that turned Microsoft into a household name.

In 1986, Microsoft went public at $21 per share, according to the NASDAQ.  A year later, Gates popped up on the billionaire list, the youngest ever to hold the status at the time, at 31 years old.

Microsoft expands its empire

Throughout the 1980s and 1990s, Microsoft’s dominance in the software industry grew rapidly, particularly with the introduction of Windows 3.0 in 1990, which sold over 60 million copies and solidified the company’s control over the PC software market.

Over the decades, Microsoft has diversified its portfolio far beyond operating systems. Its Productivity and Business Processes division now includes the ever-popular Office Suite, which caters to both commercial and consumer markets, and the business-focused LinkedIn platform.

Equally significant is Microsoft’s Intelligent Cloud segment, led by its Azure Cloud Services, now the second-largest cloud platform globally, which has transformed the way businesses manage computing infrastructure.

The strategic pivot into cloud computing has been complemented by a range of other products, including SQL Server, Windows Server, and Visual Studio.

The giant under scrutiny

The company’s journey has not been without challenges. Its rapid rise in the 1990s attracted regulatory scrutiny, leading to high-profile antitrust cases and significant fines in both the USA and Europe.

Triggered by concerns over Microsoft’s growing dominance in the personal computer market, US regulators launched a series of investigations into whether the company was actively working to stifle competition.

The initial Federal Trade Commission probe was soon picked up by the Department of Justice, which filed formal charges in 1998. At the heart of the case was Microsoft’s practice of bundling its software, mainly Internet Explorer, with the Windows operating system.

Critics argued that this not only marginalised competitors like Netscape, but also made it difficult for users to install or even access alternative programs.

From Bill Gates to Satya Nadella

Despite these setbacks, Microsoft has continually adapted to the evolving technological landscape. When Steve Ballmer became CEO in 2000, some doubted his leadership, yet Microsoft maintained its stronghold in both business and personal computing.

In the early 2000s, the company overhauled its operating systems under the codename Project Longhorn.

The initiative led to the release of Windows Vista in 2007, which received mixed reactions. However, Windows 7 in 2009 helped Microsoft regain favour, while subsequent updates like Windows 8 and 8.1 aimed to modernise the user experience, especially on tablets.

The transition from Bill Gates to Steve Ballmer, and later to Satya Nadella in 2014, marked a new era of leadership that saw the company’s market capitalisation soar and its focus shift to cloud computing and AI.

Under Nadella’s stewardship, Microsoft has invested heavily in AI, including a notable $1 billion investment in OpenAI in 2019.

The strategic move, alongside the integration of AI features across its software ecosystem, from Microsoft 365 to Bing and Windows, signals the company’s determination to remain at the forefront of technological innovation.

Microsoft’s push for innovation through major acquisitions and investments

Microsoft has consistently demonstrated its commitment to expanding its technological capabilities and market reach through strategic acquisitions.

In 2011, Microsoft made headlines with its $8.5 billion acquisition of Skype, a move intended to rival Apple’s FaceTime and Google Voice by integrating Skype across Microsoft platforms like Outlook and Xbox.

Other strategic acquisitions played a significant role in Microsoft’s evolution. The company purchased LinkedIn, Skype, GitHub and Mojang, the studios behind Minecraft. In recent years, the company has made notable investments in key sectors, including cloud infrastructure, cybersecurity, ΑΙ, and gaming.

One of the most significant acquisitions was Inflection AI in 2024. This deal bolstered Microsoft’s efforts to integrate AI into everyday applications. Personal AI tools, essential for both consumers and businesses, enhance productivity and personalisation.

The acquisition strengthens Microsoft’s position in conversational AI, benefiting platforms such as Microsoft 365, Azure AI, and OpenAI’s ChatGPT, which Microsoft heavily supports.

By enhancing its capabilities in natural language processing and user interaction, this acquisition allows Microsoft to offer more intuitive and personalised AI solutions, helping it compete with companies like Google and Meta.

Microsoft acquires Fungible and Lumenisity for cloud innovation

In a strategic push to enhance its cloud infrastructure, Microsoft has made notable acquisitions in recent years, including Fungible and Lumenisity.

In January 2023, Microsoft acquired Fungible for $190 million. Fungible specialises in data processing units (DPUs), which are crucial for optimising tasks like network routing, security, and workload management.

By integrating Fungible’s technology, Microsoft enhances the operational efficiency of its Azure data centres, cutting costs and energy consumption while offering more cost-effective solutions to enterprise customers. This move positions Microsoft to capitalise on the growing demand for robust cloud services.

Similarly, in December 2022, Microsoft acquired Lumenisity, a company known for its advanced fibre optic technology. Lumenisity’s innovations boost network speed and efficiency, making it ideal for handling high volumes of data traffic.

The move has strengthened Azure’s network infrastructure, improving data transfer speeds and reducing latency, particularly important for areas like the Internet of Things (IoT) and AI-driven workloads that require reliable, high-performance connectivity.

Together, these acquisitions reflect Microsoft’s ongoing commitment to innovation in cloud services and technology infrastructure.

Microsoft expands cybersecurity capabilities with Miburo acquisition

Microsoft has also announced its agreement to acquire Miburo, a leading expert in cyber intelligence and foreign threat analysis. This acquisition further strengthens Microsoft’s commitment to enhancing its cybersecurity solutions and threat detection capabilities.

Miburo, known for its expertise in identifying state-sponsored cyber threats and disinformation campaigns, will be integrated into Microsoft’s Customer Security and Trust organisation.

The acquisition will bolster Microsoft’s existing threat detection platforms, enabling the company to better address emerging cyber threats and state-sanctioned information operations.

Miburo’s analysts will work closely with Microsoft’s Threat Intelligence Center, data scientists, and other security teams to expand the company’s ability to counter complex cyber-attacks and the use of information operations by foreign actors.

Miburo’s mission to protect democracies and ensure the integrity of information environments aligns closely with Microsoft’s goals of safeguarding its customers against malign influences and extremism.

A strategic move that further solidifies Microsoft’s position as a leader in cybersecurity and reinforces its ongoing investment in addressing evolving global security challenges.
